My first experience photographing the eclipse. Was hoping to catch the beads, but don't seem to see any even though the Moon's edge appears to have some texture to it.

They only appear during a Total Eclipse.

I think there is too much light during an annular eclipse to see those narrow strips through the mountain tops.

They ARE indeed features of annular eclipses, too, but strong filtration is not the way to capture them.

 

Here is an article from someone who captured Baily's Beads during the August 21, 2017, total solar eclipse.  He shot UNfiltered, with a very fast (1/6000th second) shutter speed.

This article includes a photo which shows the Beads just prior to annularity.

Best wishes.

Nice info, Dan. I stand corrected!

My exposure was 1/1600th with ISO 400. It was borderline black already at that shutter speed with the solar filter on. Trying to clean the image up only reveals chromatic aberration limits on the old Tele-Tessar:

Pffft.  If I had a nickel for every time I stood corrected, I'd be a kabillionaire!

...And my legs (and rump) would be grotesquely huge!

IMO, Bailey's Beads is one of the most difficult eclipse features to capture. The links posted by Dan are very impressive.

 

You may have already seen this. Here are suggested camera exposures for Bailey's Beads along with other features.

You will see fine Baily's Beads at the annular (third photo) at this topic below: 10/14/2023 Annular Eclipse from Comfort Tx.

 

And Mr. Baily saw his beads at an annular eclipse.

If that's the beads, they are not all that different from mine , which are rather underwhelming.

At an annular eclipse in January 1981, we had a site right on the edge of the path (about 10 observers were located along a north-south baseline 50m apart). This was mid-eclipse.

 

If you are located close to the centreline of an annular eclipse a large number of beads may be seen so fast at 2nd and 3rd contact that you won't be able to time them. Close to the edge of the eclipse path they occur more slowly.

 

We used a C8 stopped down to 55mm (off-axis mask) and a projection screen. Bailey's Beads were easily seen by all (we were timing them), here's one of several shots ( in a howling gale on top of a mountain at 1500m so the scope was bouncing a lot). Yes the stopwatch was readable in most frames, and its time was checked against a shortwave time signal, before and after.
